The proton carriers are encapasulated with high mobility and provide high proton conductivity at 150C under anhydrous condition. The high proton conductivity and non-porous nature allow power generation by fuel cell in which CPs are used as electrolyte. To observe defects and mobile proton carriers, we carried out solid-state NMR, XAFS, XRD, and ICP-AES/EA. On the basis of these analyses, we elucidated that the defect sites provide space for mobile uncoordinated HPO, HPO, and HO. These mobile carriers play a key role to expand proton hopping path and promote the mobility of all protons in coordination frameworks, leading to high proton conductivity and fuel cell power generation.
